To all whom at may concern.-

Be it known that I, CARL'Ki'IHN, a subject of the German Emperor, andarcsident of Berlin, in the German Empire, have invented a certain new and useful Improved Ball-Joint, of which the following is a full, clear, and exact description.

The present invention consists ofa ball-joint for all kinds of tube, in which the spring as employed in such joints is omitted and a short piece of rubber tube or hose substituted therefor; and in order to render the present specification more easily intelligible reference is had to the accompanying drawings, in whichigure 1 tea side elevation of the joint, and Fig. 2 a vertical section through the same.

The tube end a is provided with a'curved outwardly-extending shoulder a'in the usual manner, over which the cap B is passed. The

body of the joint 0 is screwed into the cap B in the usual manner, and instead of inserting a spring, as has been hitherto done, a short piece of rubber tube or hose d is suitably fitted in between the under surface of the tube end a and the interior surface of the body of the joint 0. lar connection between the parts, which is capable of movement in any direction and sit the same time renders the whole joint gas tight.

I claim as my invention= v The combination ofan upper tubular 8X15 tension having an exteriorly-rounded shoal der (1' and downwardly-extending tube-nipple fixed thereunder, a cap B on said extension to fit over said shoulder and movable thereon, a body 0 attached to said cap and having lower extension to receive the gas-tube and inner upwardly-extending nipple, and a piece of elastic pipe or hose inserted. between said cap-supporting shoulder and the body and engaging over both said nipples substam tially as'described;

In witness whereof I have hereunto set my hand in presence of two witnesses.
